A Tutorial for the Design and Use of Assessment-Based Instruction in Practice

Assessment-based instruction can increase the efficacy and efficiency of skill acquisition by using learner data to select an intervention procedure from a comparison of potential interventions. Although there are many published examples of assessments that guide the selection of skill-acquisition procedures, there are limited resources available to practitioners to guide the development of assessments for use in practice. This article describes a sequence of steps that Board Certified Behavior Analysts can follow to design and use assessment-based instruction in practice. These steps include (a) pick a topic to evaluate, (b) identify interventions to include in the assessment, (c) identify target behavior, (d) select an experimental design, (e) select a skill and targets, (f) equate noncritical procedures across conditions, (g) design templates for data collection, (h) conduct the assessment, and (i) use assessment results to guide practice. Included in these steps are examples and materials for how to conduct components of assessment-based instruction.

Nurses and Patients' Perspectives on Spiritual Health Assessment

Nurses conduct physical and psychosocial assessments during admissions to healthcare facilities. Patients rely upon nurses to provide support and education during their journey, from periods of health decline to states of optimal wellness. Therefore, nurses are an ideal population to assess spiritual health. The value and necessity of spiritual assessment were explored on an inpatient unit providing medical and palliative care to patients. Two spiritual assessment tools, comprised each of five items, were evaluated by nursing staff and patients. Spiritual Assessment Tool 1 used language that was unaffiliated with religion, nor a belief in God, and Spiritual Assessment Tool 2 used language affiliated with faith and belief in God.

Video Commentary: Rapid-Fire Assessment of Surgical Cognitive Skills

OBJECTIVE

We describe the use of "Video Commentary", an assessment using a set of operative videos, to assess trainees' surgical cognitive skills (operative knowledge, spatial awareness, and surgical insight).

DESIGN & SETTING

The Video Commentary assessment has been routinely administered to Postgraduate Year (PGY) 1-5 general surgery residents since 2014 as part of a biannual multistation, OSCE-type exam at Mayo Clinic, Rochester, MN. Video Commentary is a rapid-fire, 6-minute assessment, where trainees watch a series of 20 to 30 second operative video clips and comment on them as they play. Each clip varies in procedure, approach, difficulty, and complexity. The combination of video clips differs according to trainees' PGY level except for a few videos that overlap among PGY groups. The name of the procedure is provided at the beginning of each clip with a countdown timer showing in the corner of the screen. A comprehensive checklist is used to score trainees' performance in real-time.

DISCUSSION

Assessment of trainees of different levels and staff surgeons show a positive correlation with the experience level (p = 0.0001). The assessment provides a safe alternative to assess trainees in the operating room and encourages them to become more effective communicators. With the use of technology, large video databases can be created to provide just-in-time tailored feedback to the trainees.

CONCLUSIONS

Video Commentary can serve as a time and resource-efficient assessment of trainees' surgical cognitive skills and insight. The use and demand of real-time commentary on operative videos may provide a viable approach to help surgeon educators determine trainees' baseline, progression, and readiness to advance.

Dysphagia in adult myopathies

Dysphagia (impaired swallowing) is not a rare problem in various neuromuscular disorders, both in the pediatric and the adult patient population. On many occasions such patients are first presented to other medical specialists or health professionals. Disorders of deglutition are probably underrecognized in patients with a neuromuscular disease as a result of patient's and doctor's delay. This review will focus on dysphagia in adults suffering from a myopathy. Dysphagia in myopathies usually affects the oropharyngeal phases which rely mostly on voluntary muscle activity of the mouth, pharynx and upper esophageal sphincter. Dysphagia is known to contribute to a reduction of quality of life and may also lead to increased morbidity and mortality. The review includes an overview on symptomatology and tools of assessments, and elaborates on dysphagia in specific hereditary and acquired myopathies.

A short report of satisfaction levels amongst Irish trainees in psychiatry with out of hours and emergency assessments

OBJECTIVES

On-call and crisis psychiatry is a very challenging aspect of psychiatric training. This study aimed to describe the experiences of psychiatric trainees on-call in hospitals, emergency departments and psychiatric units in Ireland.

METHODS

In total, 193 psychiatric trainees in Ireland were emailed a survey in 2017. The survey included questions regarding the duties expected of the trainee, frequency of on-call obligations, un-rostered hours worked, level of senior support, assessment facilities available and doctors' satisfaction with the on-call experience.

RESULTS

Overall, 68 trainees responded to the survey. In total, 35% of respondents reported dissatisfaction with their experience of on-call and crisis psychiatry, 46% reported that they were not provided with training in risk assessment and 21% of respondents stated that there was not a suitable room available to perform their assessments.

CONCLUSIONS

This survey has raised important issues facing those on the frontline of psychiatric services in Ireland. Of particular concern are resource issues faced by trainees and the need for further training and support related to risk assessment when on-call. Remedying these issues may lead to a decreased rate of dropout as well as a safer and better environment for patients and doctors alike.

Writing exceptional (specific, student and criterion-focused) rubrics for nursing studies

Effective assessment of nurses in higher education is dependent on the interpretation and demonstration of learning outcomes by students and educators/academics. Rubrics can effectively communicate unit learning outcomes to students and may contribute towards the academic rigour of nursing courses, when assessment criteria are articulated clearly and consistently to both students and educators/academics. This paper aims to describe the different types and uses of rubrics, as well as outline the steps required to develop exceptional rubrics whilst using the literature as a basis for suggestions. Well written rubrics can facilitate consistency of marking across a student cohort, which may result in decreased student anxiety regarding assessment expectations, uniformity of assessment style and layout and may ensure that educators/academics across a teaching team are interpreting assessment criteria, consistently. Exceptional rubrics can empower students to success in academic assessments.

Effectiveness of Small Group Discussions for Teaching Specific Pharmacology Concepts

Small group discussions are used in medical education to reinforce learning and to promote the application of knowledge. Small group discussions can involve a variety of tasks, such as critical thinking, self-directed learning, problem-solving, and brainstorming. The objective of this study is to find out if small group discussions can improve students' learning of specific pharmacology topics and students' performance on assessments. In the present study, small group discussions were utilized for six unique topics in the pharmacology course, and knowledge-based tests were administered before and after small group discussions to examine their efficacy. Statistically significant improvement in knowledge gains was observed for antimicrobials and neuropharmacology topics, but not for anticancer agents. Students' performance in topics that had group discussions was better on summative assessments compared with the overall performance on the summative assessment in the pharmacology (study group; summer 2018). Students' (study group; summer 2018) overall grade on the summative assessment of the pharmacology course was better than overall pharmacology grade on the summative assessment of students who had no group discussions (control group; winter 2018). Students' perceptions of the small group discussions were satisfactory, suggesting group discussions may be an enjoyable way to improve students' performance in some pharmacology topics.

High prevalence of prenatal alcohol exposure detected by breathalyzer in the Republic of the Congo, Africa

OBJECTIVE

Assess the prevalence of prenatal alcohol exposure in the Republic of the Congo by measuring breath alcohol concentration (BrAC) levels using a breathalyzer device.

METHODS

Pregnant women were assessed for alcohol use with a breathalyzer reading during two prenatal visits and during labor and delivery.

RESULTS

Among 662 pregnant women consented and screened with a breathalyzer, 192 (29.0%) had a positive BrAC during 1st trimester. During the second assessment, approximately 69% (132) of the 192 pregnant women had a second positive BrAC. A third assessment during labor and delivery identified 60 women (31%) with a third positive BrAC. About 19% (36) of the 192 pregnant women had positive BrACs at all three times. Among women who were positive on the first and second assessments, 30% had a BrAC that was above 0.07, which is almost equivalent of binge drinking (four or more standard drinks in about 2 h). The mean BrAC reading decreased as the pregnancy progressed.

CONCLUSIONS

The results of this study utilizing a unique exposure detection methodology suggest that the use of BrAC may be a useful objective option to detect and quantify alcohol consumption during pregnancy. The prevalence of alcohol use identified during pregnancy in the Republic of the Congo was increased over 20% when compared to maternal reports from a previous study. Nearly one of every five women identified at the first prenatal visit continued drinking throughout pregnancy. Urgent measures are needed to reduce alcohol consumption among this population of pregnant women.

The Overt Aggression Scale Modified (OAS-M) for clinical trials targeting impulsive aggression and intermittent explosive disorder: Validity, reliability, and correlates

While aggressive behavior is common, and a disorder of impulsive aggression has been defined in the DSM-5 (Intermittent Explosive Disorder: IED), there are no currently FDA approved interventions to reduce these behaviors. One obstacle to the development of interventions to treat aggression is the paucity of psychometrically valid measures to assess aggressive behavior in the context of clinical trials, especially those in the outpatients setting. While there are many assessment of trait aggression, very few attempt to assess current aggressive behavior over time and/or in individuals not in a closed setting. The Overt Aggression Scale Modified (OAS-M) was developed to fill this void and this paper reviews its development along with presenting new data on its validity, reliability, and correlates with related constructs. Overall, the OAS-M is a valid and reliable measure of state (e.g., week to week) aggression, has good psychometric properties, and shows evidence of change in clinical trials of agents with putative anti-aggressive efficacy.

The Multidimensional Structure of Problem Gambling: An Evaluation of Four Gambling Categorization Instruments from an International Online Survey of Gamblers

To examine the underlying dimensionality and structure of problem gambling using a comprehensive range of problem gambling assessments from an international online survey of gamblers. A total of 12,521 gamblers from 105 countries were recruited through banner advertising placed on a popular online gambling portal to take an online survey. Although participants were recruited online, the majority of the sample (71.6%) gambled only at land-based venues in the past 12 months. A total of 5081 individuals completed all items from the four problem gambling assessments. Participants were allocated to answer one of the four problem gambling assessments and the remaining unique items from the three other problem gambling assessments. The order of assessments were counterbalanced. Two optimal scaling procedures were independently employed to estimate the number of dimensions within the data: exploratory categorical principal component bootstrap analysis and multidimensional scaling. Nonlinear canonical correlation was then used to establish how well each of the four assessment instruments captured the identified dimensions. A final confirmatory principal component analysis was run to understand and characterise the nature of the dimensions that were identified. Both the categorical principal component bootstrap analysis and multidimensional scaling indicated the data was multidimensional, with four dimensions (including a single dominant dimension) providing the best characterisation of the data. The nonlinear canonical correlation analysis found that the Problem and Pathological Gambling Measure and the National Opinion Research Center DSM-IV Screen for Gambling Problems operationalization of the Diagnostic and Statistical Manual of Mental Disorders Four (DSM-IV) criteria best captured these multiple dimensions. Confirmatory principal component analysis suggest a core experience of generic problem gambling symptomology and three other components: "financial problems", "health and relationship issues", and "difficulty controlling gambling". Problem gambling symptomology appears to be multi-dimensional. Certain assessments capture this heterogeneity better than others and thereby provide a more complete and accurate assessment of this construct.

The TechSAge Minimum Battery: A multidimensional and holistic assessment of individuals aging with long-term disabilities

BACKGROUND

People with disabilities acquired in early to mid-life are living longer, contributing to growing numbers of older adults who are aging with disability, an understudied population likely to be underserved.

OBJECTIVES

This paper demonstrates the usefulness of the TechSAge Minimum Battery as a holistic assessment of health for people aging with disabilities.

METHODS

Survey data of socio-demographic and health characteristics were collected from 176 older adults with long-term vision, hearing, and/or mobility disabilities. A series of descriptive and bivariate analyses were conducted to illustrate the heterogeneity of the sample. An in-depth analysis of the subsample with vision difficulty was conducted to highlight the tool's value in assessing detailed contextual information for a specific disability.

RESULTS

Prevalence of health conditions (M = 4.1; SD = 2.5), prescription medications (M = 4.1; SD = 3.9), and serious functional difficulties (M = 1.6; SD = 0.85) indicated a fair degree of comorbidity, but with considerable variation in number and type among individuals. Subjective health ratings were high overall, but lower scores were correlated with additional comorbidities (r = -0.31-0.40, p =<.001). Analyses of the subsample with vision difficulty demonstrated heterogeneity in functional capacity, degree of impairment, duration, and use of supportive aids.

CONCLUSIONS

Findings highlighted the heterogeneity among people aging with disability and demonstrated the importance of capturing multi-dimensional factors inclusive of an individual's capacity, context, and personal factors, which the Minimum Battery provides in an integrated assessment. Potential healthcare applications of the tool are discussed with implications for bridging aging and disability services.

Common Data Element for Unruptured Intracranial Aneurysm and Subarachnoid Hemorrhage: Recommendations from Assessments and Clinical Examination Workgroup/Subcommittee

BACKGROUND

Clinical studies of subarachnoid hemorrhage (SAH) and unruptured cerebral aneurysms lack uniformity in terms of variables used for assessments and clinical examination of patients which has led to difficulty in comparing studies and performing meta-analyses. The overall goal of the National Institute of Health/National Institute of Neurological Disorders and Stroke Unruptured Intracranial Aneurysms (UIA) and subarachnoid hemorrhage (SAH) Common Data Elements (CDE) Project was to provide common definitions and terminology for future unruptured intracranial aneurysm and SAH research.

METHODS

This paper summarizes the recommendations of the subcommittee on SAH Assessments and Clinical Examination. The subcommittee consisted of an international and multidisciplinary panel of experts in UIA and SAH. Consensus recommendations were developed by reviewing previously published CDEs for other neurological diseases including traumatic brain injury, epilepsy and stroke, and the SAH literature. Recommendations for CDEs were classified by priority into "core," "supplemental-highly recommended," "supplemental" and "exploratory."

RESULTS

We identified 248 variables for Assessments and Clinical Examination. Only the World Federation of Neurological Societies grading scale was classified as "Core." The Glasgow Coma Scale was classified as "Supplemental-Highly Recommended." All other Assessments and Clinical Examination variables were categorized as "Supplemental."

CONCLUSION

The recommended Assessments and Clinical Examination variables have been collated from a large number of potentially useful scales, history, clinical presentation, laboratory, and other tests. We hope that adherence to these recommendations will facilitate the comparison of results across studies and meta-analyses of individual patient data.

BOMET-QoL-10 questionnaire for breast cancer patients with bone metastasis: the prospective MABOMET GEICAM study

Background

Bone metastasis (BM) is the most common site of disease in metastatic breast cancer (MBC) patients. BM impacts health-related quality of life (HRQoL). We tested prospectively the psychometric properties of the Bone Metastasis Quality of Life (BOMET-QoL-10) measure on MBC patients with BM.

Methods

Patients completed the BOMET-QoL-10 questionnaire, the Visual Analogue Scale (VAS) for pain, and a self-perceived health status item at baseline and at follow-up visits. We performed psychometric tests and calculated the effect size of specific BM treatment on patients´ HRQoL.

Results

Almost 70% of the 172 patients reported symptoms, 23.3% experienced irruptive pain, and over half were receiving chemotherapy. BOMET-QoL-10 proved to be a quick assessment tool performing well in readability and completion time (about 10 min) with 0–1.2% of missing/invalid data. Although BOMET-QoL-10 scores remained fairly stable during study visits, differences were observed for patient subgroups (e.g., with or without skeletal-related events or adverse effects). Scores were significantly correlated with physician-reported patient status, patient-reported pain, symptoms, and perceived health status. BOMET-QoL-10 scores also varied prospectively according to changes in pain intensity.

Conclusions

BOMET-QoL-10 performed well as a brief, easy-to-administer, useful, and sensitive HRQoL measure for potential use for clinical practice with MBC patients.

Psychometric properties of the German Version of the Pediatric Evaluation of Disability Inventory (PEDI-G): A factor analysis

BACKGROUND

Activities of daily living (ADL) are crucial for children because they enable them to participate in everyday life. For the evaluation of children`s ADL performance, health professionals such as occupational therapists use standardized ADL assessments. To implement assessments into practice it is important that the score generated from an assessment can be viewed as a unidimensional measure.

AIM

To investigate the factor structure of the German Pediatric Evaluation of Disability Inventory (PEDI-G) in a sample of typically developing children and children with an impairment.

MATERIAL AND METHODS

An exploratory factor analysis (EFA) with factor rotation was performed to assess the factor structure for the PEDI-G domains (self-care, mobility and social function) of the Functional Skills Scale and the Caregiver Assistance Scale.

RESULTS

262 children (118 (45%) girls and 144 (55%) boys) participated in this study. Their mean age (SD) was 4 years (SD 1.91). Results suggest that the PEDI domains of the Functional Skills Scale and the Caregivers Assistance Scale can be used as unidimensional measures to evaluate child`s ability to perform activities of daily living.

CONCLUSION

The results of this study support the use of the PEDI-G for research and practice in Austria, Germany and Switzerland.

Assessing Spiritual Well-Being in Residential Aged Care: An Exploratory Review

With the emerging incorporation of spiritual care into the allied health stream, there is a need for a clear and validated process of spiritual review that can be understood across multidisciplinary teams. The aim and purpose of this paper was to critically review the literature regarding spiritual screening, history-taking and assessment, and explore the merits of developing a brief instrument focussed on assessing and improving the spiritual well-being of consumers within residential aged care. Following an exploratory review of the literature, the results indicate that effective processes are noted regarding the triage and identification of the needs and spiritual assessment of consumers; however, many of these tools are overly religious in content, unwieldy in size, or not specifically aimed at identifying the immediate crisis confronting the consumer. It is recommended that an assessment instrument be developed which is communicable across all allied health practitioners (including spiritual carers), which may contribute towards a taxonomy of common consumer conditions, and which will enable the development and delivery of more targeted care plans.

What do care home managers believe constitutes an 'assessment for frailty' of care home residents in North-West London? A survey

Background

Frail individuals are at risk of significant clinical deterioration if their frailty is not identified and managed appropriately. Research suggests that any interaction between an older person and a health or social care professional should include an assessment for frailty. Many older care home residents are frail when admitted, but we have little knowledge of whether or how this is assessed. The aim of this paper is to understand and establish the characteristics of the reported ‘assessments for frailty’ used in care homes with nursing (nursing homes) across North-West London. This will help understand what an ‘assessment for frailty’ of care home residents mean in practice in North-West London.

Methods

Telephone contact was made with every Care Quality Commission (CQC) (independent regulator of health and adult social care in England) regulated nursing home across North-West London [n = 87]. An online survey was sent to all that expressed interest [n = 73]. The survey was developed through conversations with healthcare professionals, based on literature and tested with academics and clinicians. Survey responses were analysed using descriptive statistics. The Mann-Whitney U test was used for statistical analyses.

Results

24/73 nursing homes completed the survey (33%). Differences in the characteristics of reported ‘assessments for frailty’ across nursing homes were evident. Variation in high level domains assessed (physical, social, mental and environmental) was observed. Nurses were the most common professional group completing assessments for frailty, with documentation and storage being predominantly paper based. A statistically significant difference between the number of assessments used in corporate chain owned nursing homes (3.9) versus independently owned nursing homes (2.1) was observed (U = 21, p = .005).

Conclusions

Great variation existed in the characteristics of reported ‘assessments for frailty’ in nursing homes. Our study suggests that not all physical, social, mental and environmental domains of frailty are routinely assessed: it appears that frailty is still primarily viewed only in terms of physical health. The consequences of this could be severe for patients, staff and healthcare settings. Research illustrates that frailty is a broad, multifactorial health state and, as such, an overall ‘assessment for frailty’ should reflect this.

Nonsynostotic plagiocephaly: a child health care intervention in Skaraborg, Sweden

Background

The aim was to evaluate the intervention’s effect on prevention and reversal of nonsynostotic plagiocephaly.

Methods

Thirty-eight intervention group nurses were educated about nonsynostotic plagiocephaly and asked to follow guidelines; 18 control group nurses were not. In a longitudinal single-blinded clinical intervention, parents brought infants to well-child visits according to the national schedule. Cranial shape was assessed in 176 intervention and 92 control group infants at 2-, 4-, and 12-month visits.

Results

Asymmetry at two months reversed by four months four times more often in intervention than control subgroup infants (OR = 4.07, p = 0.02) when adjusted for parent awareness of written information from their nurse. Asymmetry at two months reversed by 12 months fivefold when parents were aware of written information (OR = 0.19, p = 0.04). The risk for persistent asymmetry at 12 months was lower for intervention than control group infants (RR = 0.35, p = 0.03). Of infants with no asymmetry at two months, 25% in intervention and 22% in control group developed brachycephaly.

Conclusions

The intervention contributed to early reversal and reducing infants’ risk for persistent asymmetry. Parents’ awareness of written information contributed to reversal. Preventing brachycephaly was difficult. Further research is needed.

Ambulatory care preceptors' perceptions on SOAP note writing in advanced pharmacy practice experiences (APPEs)

INTRODUCTION

Descriptions of SOAP note requirements and assessment methods used during advanced pharmacy practice experiences (APPEs) are limited in the literature. This study aimed to gather information from preceptors regarding SOAP note writing and assessment methods utilized during ambulatory care APPEs.

METHODS

A survey was developed and distributed to ambulatory care preceptors with data collected via Qualtrics and analyzed using descriptive statistics, Fisher's exact test to assess the significance for associations between dependent and independent variables, and the Gamma test to assess dependent variables in grading habits and feedback types.

RESULTS

The survey response rate was 62% with 75% of preceptors having students write SOAP notes during APPEs. A majority of preceptors (84%) do not formally grade SOAP notes with full-time faculty being more likely to grade and provide written feedback. Half of the preceptors perceived students as either prepared or very prepared to write SOAP notes but the majority felt that students struggle with the assessment portion of the note. There were significant differences between schools in the percentage of preceptors that formally grade SOAP notes, ranging from 2 to 45%.

CONCLUSIONS

Preceptors' perception of student preparedness to write SOAP notes on ambulatory APPEs was similar, despite assessment methods varying widely.

Assessing trauma in a transcultural context: challenges in mental health care with immigrants and refugees

The growing numbers of refugees and immigrants from conflict-prone areas settling throughout the world bring several challenges for those working in the mental health care system. Immigrants and refugees of all ages arrive with complex and nuanced mental health histories of war, torture, and strenuous migration journeys. Many of the challenges of addressing the health care needs for this growing population of immigrants and refugees are often unfamiliar, and thus practices to address these challenges are not yet routine for care providers and health care organizations. In particular, complex trauma can make mental health assessments difficult for health care organizations or care providers with limited experience and training in transcultural or trauma-informed care. Using a transcultural approach can improve assessment and screening processes, leading to more effective and high-quality care for immigrant and refugee families experiencing mental health disorders.

This paper presents findings from an assessment of current mental health services focusing on current practices and experiences with immigrant and refugee patients and families. The difficulties in developing shared understandings about mental health can hinder the therapeutic process; therefore, it is imperative to ensure an effective assessment right from the beginning, yet there is limited use of existing cultural formulation tools from the DSM-IV or DSM-5. The paper outlines current practices, approaches, challenges, and recommendations shared by mental health care providers and program leaders in addressing the mental health care needs of immigrants and refugees. The results from this study demonstrate that there are many challenges and inconsistencies in providing transcultural, trauma-informed care. Respondents emphasized the need for a thorough yet flexible and adaptive approach that allows for an exploration of differences in cultural interpretations of mental health. Our study concluded that ensuring a mindful, reflexive, transcultural, and trauma-informed health care workforce, and a learning environment to support staff with education, resources, and tools will improve the health care experiences of immigrants and refugees in the mental health care system.

Application of 3D-printed and patient-specific cast for the treatment of distal radius fractures: initial experience

BACKGROUND

Distal radius fracture is common in the general population. Fracture management includes a plaster cast, splint and synthetic material cast to immobilise the injured arm. Casting complications are common in those conventional casting technologies. 3D printing technology is a rapidly increasing application in rehabilitation. However, there is no clinical study investigating the application of a 3D-printed orthopaedic cast for the treatment of bone fractures. We have developed a patient-specific casting technology fabricated by 3D printing. This pioneering study aims to use 3D-printed casts we developed for the treatment of distal radius fractures, to provide the foundation for conducting additional clinical trials, and to perform clinical assessments.

METHOD

Ten patients with ages between 5 and 78 years are involved in the clinical trial. Patients are applied 3D-printed casts we developed. Orthopaedic surgeons carried out a six-week follow-up to examine clinical outcomes. Two questionnaires were developed for the assessment of clinical efficacy and patients' satisfaction. These questionnaires are completed by physicians and participating patients.

RESULTS

A 3D-printed cast creates a custom-fitted design to maintain the fractured bone alignment. No loss of reduction is found in all patients. Compartment syndrome and pressure sores are not present. Patient comfort gets positive scores on the questionnaire. All (100%) of the patients opt for the 3D-printed cast instead of the conventional plaster cast.

DISCUSSION

A patient-specific, 3D-printed cast offers a proper fit to immobilise an injured arm and holds the fracture reduction appropriately. A custom-fitted structure reduces the risk of pressure-related complications due to the high and concentrated local stress. The ventilated and lightweight design minimises interference with a patient's daily activities and reduces the risk of cutaneous complications. Patients express a strong preference for using a 3D-printed cast instead of a plaster cast. Limitations of the novel cast include a slight odour after heavy sweating and the relatively high cost due to the limitations of current 3D printing technologies.

CONCLUSIONS

This pioneering study is the first clinical trial on the application of a 3D-printed cast for the treatment of forearm fractures. The novel casting technology heals the fracture effectively without casting complications. The 3D-printed cast is patient-specific and ventilated as well as lightweight, and it features both increased patient comfort and satisfaction.

Evaluation of feedback given to trainees in medical specialties

The aim of this study was to evaluate the quality of feedback provided to specialty trainees (ST3 or higher) in medical specialties during their workplace-based assessments (WBAs). The feedback given in WBAs was examined in detail in a group of 50 ST3 or higher trainees randomly selected from those taking part in a pilot study of changes to the WBA system conducted by the Joint Royal Colleges of Physicians Training Board. They were based in Health Education Northeast (Northern Deanery) and Health Education East of England (Eastern Deanery). Thematic analysis was used to identify commonly occurring themes. Feedback was mainly positive but there were differences in quality between specialties. Problems with feedback included insufficient detail, such that it was not possible to map the progression of the trainee, insufficient action plans made and the timing of feedback not being contemporaneous (feedback not being given at the time of assessment). Recommendations included feedback should be more specific; there need to be more options in the feedback forms for the supervisor to compare the trainee's performance to what is expected and action plans need to be made.

Control versus Complexity: Approaches to the Carbon Dioxide Problem at IIASA

Control versus Complexity: Approaches to the Carbon Dioxide Problem at IIASA. In the 1970s and 1980s the International Institute for Applied Systems Analysis (IIASA) hosted several research projects, workshops and conferences in order to discuss the implications of rising carbon dioxide concentrations in the Earth's atmosphere. A number of distinguished scholars, some of whom later became prominent protagonists within the United Nations' Intergovernmental Panel on Climate Change (IPCC) and sustainability communities more generally, participated in these debates. Since those at IIASA did not engage in obviously related fields such as geophysics or climatology, there is a need to explain how, and via which contexts the issue entered the institute's agenda. This article examines this historical context and contrasts two competing paradigms that emerged at IIASA in order to assess and respond to the carbon dioxide question: The first approach was related to the organisation's research projects on the future of energy systems, which drew on physics, engineering, economics and applied system dynamical modeling; the second approach drew earlier research into ecological management and complex dynamical systems theory, and argued for the use of multiple methods to assess the carbon dioxide question. The first approach invoked ideas of techno-economical control mechanisms, the second resulted in a more embedded framing of climate change as one of a larger complex of issues relating to sustainable development. Based on resources from IIASA's research repositories and institutional archive, this study retraces these competing discourse framings and outlines the specific research and modeling strategies, policies, and cultural and technological imaginaries related to them.

Assisting Hand Assessment and Children's Hand-Use Experience Questionnaire -Observed Versus Perceived Bimanual Performance in Children with Unilateral Cerebral Palsy

AIMS

To explore the differences, relationship, and extent of agreement between the Assisting Hand Assessment (AHA), measuring observed ability to perform bimanual tasks, and the Children's Hand-Use Experience Questionnaire (CHEQ), assessing experienced bimanual performance.

METHODS

This study investigates a convenience sample of 34 children (16 girls) with unilateral cerebral palsy aged 6-18 years (mean 12.1, SD 3.9) in a cross-sectional design.

RESULTS

The AHA and CHEQ subscales share 8-25% of their variance (R²). Bland-Altman plots for AHA and all three CHEQ subscales indicate good average agreement, with a mean difference approaching zero but large 95% confidence intervals. Limits of agreement were extremely wide, indicating considerable disagreement between AHA and CHEQ subscales.

CONCLUSION

AHA and CHEQ seem to measure different though somewhat related constructs of bimanual performance. Results of this investigation reinforce the recommendation to use both instruments to obtain complementary information about bimanual performance including observed and perceived performance of children with unilateral cerebral palsy.

Live weight, conformation, carcass traits and economic values of ram lambs of Red Maasai and Dorper sheep and their crosses

Meat production is the most important trait in the breeding objectives of sheep production in East Africa. The aim of this study was to investigate breed differences in live weight, conformation, carcass traits and economic values for meat production among Red Maasai and Dorper sheep and their crosses. In total, 88 ram lambs, which were reared at the ILRI experimental station, Kapiti plains Estate in Central Kenya, were used for the study. The lambs were slaughtered at Kenya Meat Commission (KMC) at about 1 year of age. Prior to slaughter, the lambs were weighed, measured and assessed by experienced evaluators, and at the abattoir carcass traits were recorded. Large breed differences were found for most traits. Dorper lambs were heavier at delivery for slaughter and had better carcass grade but lower dressing percentage and fat levels than Red Maasai. Crossbreds were generally better than the parental breeds. Evaluators were willing to pay more for the Dorper lambs for slaughter although carcass weights later were shown not to be higher than for Red Maasai. Evaluators undervalued Red Maasai lambs by 8-13 % compared to Dorper lambs according to the prices quoted per kilogramme live or carcass weight by KMC. Live weight was better than any other live measure in predicting carcass weight. Due to the overall higher ranking of the crossbred lambs for meat production, Dorper may be useful as a terminal sire breed for crossing with Red Maasai ewes.
